The 270 Weatherby Magnum has been a flat-shooting favorite since Roy Weatherby first brought it to market, and this load pairs that fast, hard-hitting case with one of the most talked-about monolithic bullets around. The 134-grain Hammer Custom is a solid copper projectile designed to drive fast, hit hard, and put game down cleanly without a speck of lead. At the muzzle it moves at 3,300 fps and carries 3,240 ft-lbs of energy, with a G1 ballistic coefficient of .425 that helps it hold its speed downrange.
Hammer bullets are turned on a CNC lathe from a solid copper blend, then weighed and micrometer-measured as they come off the line. That kind of quality control is why so many hunters rave about their accuracy, often matching or beating premium cup-and-core bullets on paper. On impact, the hollow point opens up and sheds its petals right away, sending copper fragments outward to tear through vital tissue while the blunt-nosed shank keeps driving for deep, straight-line penetration. It is the best of both worlds: the dramatic wound channel of a fragmenting bullet and the penetration of a tough mono.
The 270 Wby Mag has always been about speed and reach, and the lighter-for-caliber 134-grain Hammer leans right into that. Pushed at 3,300 fps, it stays flat enough that a 300-yard zero only drops about 8.7 inches at 400 and keeps better than 2,200 fps and 1,460 ft-lbs all the way out to 500. This is a load built for open-country deer, antelope, and similar big game where a flat trajectory and reliable expansion matter. If you shoot in areas where copper is the call, you get top-shelf terminal performance without giving up anything in the field.
Field reports on Hammer bullets have been strong across North America and beyond, with hunters pointing to quick kills, minimal meat loss, and the kind of consistency you want when the shot counts.
This load shines on open-country big game like deer, antelope, and similar species where a flat trajectory and dependable expansion count. The 134-grain copper Hammer bullet sheds its petals for a wide wound channel while the shank penetrates deep, so it works well on both close and longer shots. Hunters consistently report quick, clean kills with very little meat damage.
Yes. The Hammer Custom is machined from a solid copper blend with no lead core, making it a true lead-free hunting bullet. That construction also helps it hold together for deep penetration while the nose petals break away to create additional tissue damage.
It leaves the muzzle at 3,300 fps, and with a 300-yard zero it drops roughly 8.7 inches at 400 yards. The bullet still carries well over 2,200 fps and more than 1,460 ft-lbs of energy out to 500 yards. The .425 G1 ballistic coefficient helps it buck wind and hold velocity downrange.
They have a strong reputation for it. Because each bullet is CNC-turned from solid copper, then weighed and measured for consistency, many shooters find they match or beat premium cup-and-core bullets on paper. The patented driving band design also reduces fouling and barrel friction.
